Title: Viterbi decoder
Inventor: OSAWA HIDEKAZU
IPC: H03M13/41
Filed: 1986-02-19
Abstract: PURPOSE:To discriminate surely synchronization/asynchronization with a simple hardware without being affected by S/N of a communication line, by calculating a state metric from a normalized branch metric and deciding synchronization/ asynchronization in accordance with the degree of increase of the calculated state metric. CONSTITUTION:A branch metric calculating circuit 14 calculates four branch metrics in accordance with soft deciding data rI and rQ corresponding to received channel bits SI and SQ. Branch metrics are distances between soft deciding data rI and rQ and each branch. A minimum branch metric is subtracted from four branch metrics by a normalizing circuit 15. By this normalization, the change to S/N of the increase rate of the state metric is opposite between the synchronizing state and the asynchronizing state. Thus, a threshold is set easily even if S/N of a transmission line is not settled when the increase rate of the state metric is compared with the threshold to decide synchronization/ asynchronization.

Title: Optical recording medium film
Inventor: YASUDA NOBUROU
IPC: G11B7/24
Filed: 1983-03-04
Abstract: PURPOSE:To obtain a medium film having high sensitivity, high reliability and a long life by incorporating the components of an alkyl metal consisting of an alkyl molecule and a metal having a high m.p. in a medium film. CONSTITUTION:A metallic plate 4 and a substrate 5 are preliminarily disposed in a vacuum vessel in such a way as to face each other and an Ag plate having >=600 deg.Cm.p. is used for the plate 4. Gaseous methane is used for gaseous paraffinic hydrocarbon and gaseous Ar for inert gas. When electric discharge is generated, the gaseous methane is dissociated to generate a -H group, -CH3 group, -H2 group, -CH2 group, etc. which collide against the Ag plate and alkyl metals such as Ag-H, Ag-CH3, Ag-H2, Ag-CH2, etc. are formed as a result of reaction. The film in which Ag atom, alkyl Ag, and alkyl molecule exist mixedly is formed on the substrate. When a laser beam is rediated to the film, the alkyl molecule contained in the Ag-C film evaporates and changes to an Ag film 13 at about 180 deg.. The naturally oxidized film is as thin as several nm and once the film is formed, the film is no longer oxidized and is extremely stable. The stability after recording is therefore extremely high and the long-term presservation of a record is made possible.

IPC: B65B45/00
Filed: 1978-03-24
Abstract: PURPOSE: To provide an automatic stretch packing machine free from the generation of shrinkages at the completion of packing.  
     CONSTITUTION: In a method of packing in which the end of a film 13 is tucked into the bottom side being stretched after the intended article 25 is rolled therewith, film retaining sections 14 and 15 are provided above and below a film welding/cutting device 37. A plurality of guide rollers 16 to 25 are so arranged as to guide a film drawn in front of the device from the retaining sections 14 and 15, in such a manner that at least one 18 of the guide rollers employs a roller 7 with a friction adjusting mechanism for controlling the tension of the film. Since a roller body 30 is subjected to a braking force due to a slide between a flange 29 and washer 31 caused by the force of a compression spring 34 while the film is drawn out, it increases the tension of the film so considerably that the roller stretches to a certain extent when the article is rolled. Therefore, the roller can't be used beyond the minimum necessary length thereby eliminating shrinkages on the surface of the article.

Filed: 1994-03-07
Abstract: PURPOSE:To detect the acceleration in the directions of three axes with a single sensor by supporting a weight in square plate of poly Si for forming Z-axis movable electrode between the Si substrate of X/Y-axis surfaces and the upper electrode plate of poly Si which becomes the fixed electrode of Z axis with the beam of each corner and then converting the displacement in weight to the increase/decrease in the electrostatic capacity between the electrodes. CONSTITUTION:When an acceleration in X-axis direction is applied to a weight 31, a beam 34 is deflected in X-axis direction with the support point at the other edge part as a support, the weight 31 is displaced in X-axis direction and the electrostatic capacity between a movable electrode 32X and a fixed electrode 35X increases, and the electrostatic capacity between the electrodes 32X and 36X decreases. The amount of change of the electrostatic capacity is taken between terminals S0 and SX1 and between terminals S0 and SX2, thus detecting the acceleration in X-axis direction. Also, in a similar manner. the amount of change in the electrostatic electricity due to the application of acceleration in Y-axis and Z-axis directions to the weight 31 is taken between terminals S0 and SY1 and between terminals S0 and SY2 and then between terminals S0 and SZ1 and between terminals S0 and SZ2, thus detecting the acceleration in X-axis and Z-axis directions.

IPC: G01M13/02
Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To measure only torque distribution ratio with a compact exclusive measuring apparatus having improved maneuverability by obtaining a ratio of a resistance value of a brake device having a controlled brake force acting on two output shafts of a slip limiting differential gear to the output torque of a variable speed motor. SOLUTION: The torque of a variable speed motor 1 is transmitted to left and right transmitting shafts of a slip limiting differential gear (differential gear) housed in a slip limit differential gear receiving housing through a torque converter 3 and a gear box 5. On the other hand, brake force controllers 15, 16 make the shaft displacement act on brake devices 13, 14 on the basis of electric commands from a controller 20 so that a predetermined brake force acts as the resistance on the output shaft of the differential gear through torque converters 9, 10.  Thus, when the output torque from the motor 1 and the torque outputted to the output shaft of the differential gear are measured relative to a preset resistance value by the torque converters 3, 9, 10 to obtain the distribution ratio, the performance of the differential gear having the measured torque distribution ratio can be estimated.

Abstract: PURPOSE:To contrive the miniaturization of a head positioning mechanism, the improvement of assemblability and the reduction of cost by arranging a slit member with a slit pitch set nearly the same as the track pitch of a concentric circle-shaped track on a magnetic disk between a photo-detecting means and the magnetic disk. CONSTITUTION:A slit plate 7 consists of the material of a low reflection factor, and is constituted so that the opening part of nearly the same width as the track of the low reflection factor on the magnetic disk and the dark part 9 (part consisting of low reflection factor material) of nearly the same width as a high reflection factor track on the magnetic disk are arranged alternately. The track pitch of each opening part of the slit plate 7 is set nearly the same as the track pitch of a track mark. Accordingly, even if the quantity of light from a light source 1 is a little, the quantity of light inputted to an optical sensor 5 becomes the quantity of light of the sum of reflected light from plural opening parts, and becomes the quantity of light enough for the optical sensor 5 to operate. Thus, the optical sensor need not be of high output and high sensitivity, and the reduction of cost can be contrived.
